Primary healthcare in rural China is underutilised, especially in village clinics in Southwest China. The aim of this study was to explore any relationships among the ethnicity of the healthcare provider, the clinical competence of the healthcare provider, and the utilisation of village clinics in Southwest China.This cross-sectional survey study involved 330 village healthcare providers from three prefectures in Yunnan Province in 2017. Multiple logistic regressions were adopted to investigate the utilisation of primary healthcare among different ethnic healthcare providers.Primary healthcare utilisation was higher in village clinics where healthcare providers were Han Chinese than those where healthcare providers were ethnic minority (151 vs 101, P=0.008). The logistic regression analysis showed that clinical competence was positively associated with the utilisation of primary healthcare (odds ratio [OR]=1.49, 95% confidence interval [CI]=1.12-2.00; P=0.007) and that inadequate clinical competence of ethnic minority health workers may lead to a lag in the utilisation of primary healthcare (OR=0.45, 95% CI=0.23-0.89; P=0.022).Our results confirm differences in the utilisation of primary healthcare in rural Yunnan Province among healthcare providers of different ethnicities. Appropriate enhancements of clinical competence could be conducive to improving the utilisation of primary healthcare, especially among ethnic minority healthcare providers.

In a double blind placebo-controlled study rotavirus vaccine RIT 4237 was offered to young infants after the fourth week of life. The vaccine was very well tolerated. Fifty-seven out of 100 vaccine recipients and 10 out of 103 placebo recipients developed rotavirus-IgM-antibodies during the 1 month follow-up period. During a 6 month follow-up, stool samples from 2 out of 12 vaccinees and from 5 out of 12 placebo recipients contained rotavirus.

During the first month of life 28 full-term newborns were breast-fed (18 males and 11 females). Thereafter 8 infants continued breast-feeding while the remainder were randomly fed on either an adapted milk formula (n=13) or a soy-formula (n=7). At five months, after an oral dose of RIT 4237 rotavirus vaccine of bovine origin was given, growth and IgM/IgG type antibodies against rotavirus were measured. Weight gain was similar in all infants. There were 2 IgM and 1 IgG responders out of 7 soy fed infants, compared with 4 out of 8 human milk fed (both IgM and IgG) and 7 out of 13 IgM and 6/12 IgG formula fed infants responding to vaccination. This observation confirms previous results obtained with polio, diphtheria tetanus and pertussis vaccines indicating that soy-protein formulas may interfere with immunization processes.
